To all whom/15 may concern:

Be it known that I, VILLLAM H. EYNON, a citizen of the United States,residing'at Cleveland, inthe county of Cuyahoga and State of Ohio, haveinvented certain nei/v and useful Improvements in Machines for MakingChain Mesh, of which the following is a specification.

My invention relates to improvements in machines for making chain-mesh,the present embodiment of the invention being particularly designed forthe manufacture of chain-mesh for. use as a liexible armor such as thatdisclosed in my patent for an armored tire` granted July 12, 1910, No.963,882. p

@Wing to the laborious processes or methods of manufacture of chain-meshnow in use the prices of such chain-mesh are such as to render its useprohibitory as an armored fabric in tires, and for use in other arts.The greater quantity of chain-mesh non on the market is made by hand,and theK primary object of this invention is to pro` vide a generallyimproved machine for the manufacture of chain-mesh which will beexceedingly simple in construction, eilicient 1n operation, and adaptedto improve andV cheapen the product for the purposes above referred to.

The -Wire used for the manufacture of chain-mesh asa flexible armor foruse in pneumatic tires is of about 22 gage, (Bin mingham) andapproximately 28/l000 `of an inch Vin diameter, and the chain-mesh asproduced by this machine is of exceedingly close-mesh, the rings orlinks being of apa proximately i5/100il an inch outside diameter. Theprinciples of the machine, however, are such that the relative size andproportion of the parts may be readily modied for the production ofchain-mesh of any de sired mesh and gage.

lVith `the above mentioned ends in View, the invention consists in thenovel construction, arrangement, and combination of parts, hereinafterdescribed, illustrated in one of its emb(aliments in the accompanyingdrawing, and particularly pointed out in the appended claims.

Referring to the drawings, forming a part ot' this specification,Figurev 1 is a top plan view of a machine constructed in accordance withinvention. 2, a side elevation of the samef- 3, an enlarged cross-seo`tion and acting as` guide-teet :vation of a frame.

Similar numerals of reference designate like parts throughout all thefigures of the drawings. l

The improved machine in its present embodiment comprises a bed or frame1, con-l sisting, in the present instance, of end bearing. portionsconnected by an intermediate elevated or bridge portion la. The endbearing portions 1 are, each provided .With a'pair.

0f housing-frames er standards 2, each of. Said. housingffr'ames beineprovided with the4 usual bearing guide `'Ways containing lioii'erstationary bearings 3, and upper movable bearings 4. The Vlower orstationary llO bearings 3 are provided with a driving-shaft and theupper or movable bearings 4 are provided with a vertically movable orsec-- ond shaft 6. The shafts 5 and 6 are geared together by means ofgear-wheels 7 at one end, and are provided at; their other endwith wirefeed-rolls 8. Each ofsaid feedrolls is provided about its periphery witha pair of wire-receiving bearing grooves 8, saidfeed rolls beinginterchangeably mounted upon the ends of the shaft so that should one ofthe bearing grooves become worn the feed-roll may be reversed so as tobring the companion bearing groove into use. As a means for adjustingthe upper or second shaft 6, and particularly the tension of the upperfeed-rollsupon the lower feed-rolls,

^' loose bevel-gears 11, adapted to drive -suitable clutch mechanism,hereinafter described, said bevel gears meshing with a second set ofbevel-gears 12, carried upon a longitudinally extending driving shaft13, mounted in suitable bearings 14, on the bed 1. "1`he shaft 13,isdriven by means of a gear-wheel 15, meshing with a pinion 16, carriedupon one end of a main driving shaft 17, mounted in suitable bearingsA1S, at the rear of one of lthe bearing ends of the frame. The maindriving-shaft 17, is provided at one end with a xed driving pulley 19,and an idle or loose pulley 20, said pulleys being adapted to carry abelting communicating with any suitable and convenient source of power.

,The wire ,feed-rolls S are adapted to be alternately thrown into andout of gear with the driving mechanism, as hereinafter described, andthe wire is adapted to pass through suitable guides 21, in front of eachpair of feed-rolls, said guides acting to direct the wire in properposition between the bearing Grooves, and as the wire passes between thecaring grooves 8il of the feedrolls the latter force the wire throughthe spiral forming dies or coiling mandrels 22 at the rear. The coilingmandrel is provided on its periphery with a longitudinally extendinggroove 23, adapted to receive the wire fed from thefeed-rolls S, saidgroove terminating in a spirally arranged portion 23, sov as to form, inconnection with the incasing shell or supporting sleeve 24, thenecessary spiral path for the wire as the same is forced therethrough bymeans of the feed-rolls. The supporting sleeve is removably mounted andsecured in a bearing-lug 25 by means of a set-screw 26. The coilingmandrels 2 2 may be keyed or otherwise renoeaaio movably secured withinthe supporting sleeves 24 as desired.

141s a means for holding and securing the formed spiral coil orthelix inproper position during the chain-mesh forming operation, as hereinafterdescribed, a pairof guide members 27, are slidably mounted onA theintermediate or bridge portion 1a, of the bed, as hereinafterdescribed,l said guide members being provided with upwardly extendingflange or jaw portions 27a, extending intermediate the ceiling mandrels'22, as shown most clearly inlfig.` 2, of the drawings. The jaw portionsof the guide members are grooved on their inner sides so as to form anintermediate coil or helix receiving groove 2S, the ends of saidreceiving groove being in the same plane with said coiling mandrels andbeing adapted to .receive the formed coil or helix as' projectedtherefrom.

Cutting guide-teeth 29 project or extend i into said helix-,receivinggroove, said guidef teeth being formed,'in the present instance,

along the edge of a pair of cutting members 30, abutting againsteachother and secured, in the present instance, on the inner sides ofsaid guide members by means of a series of screws 31. The guide members27 are provided with friction-bearing base portions 32, confined andsliding within friction ways of adjustably mounted guideplates The guidemembers 27 are adapted to be adjusted with respect to each other bymeans of'the adjustably mounted guideplates through the medium of theadjusting-bolts 34 and yadjusting thumb-bolts 35.

As a means for reciprocating the guide members 27, in oppositedirections, together with the attached cutting guide teeth 29, the baseportions of the guide members are provided with depending plates 3G,provided on their inner sides with oppositely disposed friction bearingrecesses 37, said friction recesses containing oppositely disposedfriction-lugs 38, on one end of a vertically arranged shaft 39. Thelower end of the shaft 39, is provided with an operating lever 40,projecting in front of the bed portion la, of the machine by which leverthe shaft 39, may be oscillated whereby the guide members 27, andatt-ached cutting teeth may be 'reciprocated in an obvious manner. Whenthe operating lever 40, extends in its normal position as indicated inthe drawings the cutting guide-teeth. 29, are in registry with each intoengagement with the adjacent jaw-cob lar portion .113, of the adjacentbevel-'gear .11, said shifting lever being. automatically engaged andheld when thus manually shifted by the means now described. 'As a meansfor holding the shifting'A lever *42, against the resistance of thelever spring 43, so that the clutch will be held inits engaged positionfor the 4desired length of time, as hereinafter explained, a springresisted trip latch 44, is pivotally mounted in a recess of -ahorizontally extending carrier .shaft 45,

said spring latch being adapted to automatically engage the free end ofsaid lever when manually shifted as above mentioned. .i

As a means for releasing the shifting lever 42, and t-hus throwing therespective feedrolls 8 out of operation when the wire helix Jhas beenprojected to tle opposite end of the guide groove 28 of theguide'members 27. a

threaded timer shaft 46 is mounted beneath the carrier shaft in lugs 47,said threaded shaft being revolved by means of a pinion 48, meshing witha gear-wheel 49, carried by the adjacent driving-shaft 5. A carriageblock is slidably mounted upon the carrier shaft 45, and is adapted tobe longitudinally driven on the carrier shaft 45 by means of a dependingportion 50a, having a threaded face held in engagement with thethreaded.

timer shaftby means of a counter-weighted lever 51. As the carriageblock travels along the carrier shaft itis adapted during the concludingportion of its travel to engage the bevel portion 44. of the trip latchand des press the lat-ter whereby the. same disengages the shiftinglever 42, and the lever spring 43 throws the jaw-clutch out ofengagement thereby stopping the respective feedsrolls at the pointdesired. The operator then moves the operating lever 40, to one sideuntil one of the stops 52, isbrought into engagement with the adjacentbed portion 1, this movement reciprocating the cutting members inopposite directions whereby the guide cutting teeth 29, are thro-Wn outof their registering. position to cut thev intermediate coils orconvolutions of the helix. Fig. fl, shows the intermediateposition ofthe .cutting teeth'29, just after having severed the intermediate coilsor jconvolutions of the helix. This position of the guide cuttingY teethtakes place during the intermediate travel of the operating lever 40,and a further movement of the operating lever 40, carries the guidelcutting teeth to aim-thor position whereby the adjacent cuten'ds of 'thecoils or convolutions are brought into registry with each other formingthe rings 53 of the chain-mesh.' As t-he elasticity or spring in therings will' have a tendency to retract the adjacent cut ends.- whenrelieved of the pressure of the cutting teeth, the

throw or reciprocation of the cuttin teethi may be-regulated so as tocarry the a jacent.'

ends slightly pastthe registering position so that when the cuttingteeth are retracted to their normal position the cut ends will becarried .by thel elasticity of the rings into exact registry witheachother. When the rings are thus formed the operating lever is thrownback to its normal position-whereby the cutting members 30, arereciprocated to bring the guide teeth '29, into registry with each otheras shown in Figs. 1, 2, 3 and 5, of the drawings. 1

As a means for elevating the formed rings 53, apair of gripping rollers54, preferably covered with felt, are mounted immediately above thethroat portion 27h, leading from the helixl receiving groove orpassage-way 28, of the guide members 27, said gripping rollers 54, beingsuitably mounted and carried by bearing bracket plates 55, provided withav rearwardly extending plate 5G, adapted to conduct or carry thefinished chain-mesh to the rear of the machine. The bearing bracketplates 55,v together with the attached guide-plate 56, may Ibe'supported in any suitable and convenient manner, as by attachingbrackets 57 and as a means for revlolvingthe gripping rollers 54 forelevating the formed links and holding the same in proper positionforreceiving the coils or c'onvolutlons of the forming helix as thelatter passes through v the helix groove or guide-way-28, and throughthe meshes or .openings of the most recently formed rings as indicatedin Fig.. 10, a pair of meshing toothed wheels 58, ma

(see Fig. 8). said `wheels having their teeth vadapted to engage gearteeth or cog-pins 5.9, on the ends of the gripping rollers, motion beingtransmitted to said toothed be mounted upon-one of thebrackebplates 55,

wheels by a dratchet wheel 60, provided with a pinion portion 61,meshing with one of the toothed wheels 58. The ratchet wheel .60, isadapted to be given an intermittent motion by meansof a hand lever .62,provided with a pawl 63, for coperating with the ratchet wheel 6 0.,vThe length of the throw of the hand-lever 62, isadapted to be limited`and:A regulated by means of adjustably. mounted stop plates 64, wherebythe elevation 'ofthe chain mesh or link fabric, andthe most recentlyformed rings from the throat portion 27", of the guide members 2,?, maybe vregulated for the purposes hereinbct'ore referred to. Thevouter orfront gripping roller 54, is carried in depending brackets 65, carriedupon a connecting bar (SG, extending between the bracket -plates, saiddepending brackets being adapted to press the outer or front grippingroller 54, toward the opposite or cooperating roller by means ot coiledsprings (3T, on the bar 6b', and cooperating with the brackets G5 in anobvious manner, whereby the cooperating gripping rollers 54 arerevolvedtoward each otherto engage and elevate Vthe formed links 53 ofYthe fabric below, it being understood that the initially Jformed row oflinks or rings upon the commencement of the formation of the fabric maybe manually elevated and held in position for receiving the projectingwire helix hereinafter described and then manually elevated between thegripping rollers 54, after which the fabric may be cle fated atintervals by the hand lever 62, in th@ fabric forming operation.

Av\t'tcr the elevation of the formed rings,

as above described, the opposite feed-rolls are brought into operationto project the wirehelix through the guide members 27, in an oppositedirection and through the openings or meshes of the formed rings, ashereinbetorc described. Before shitting the respective shitting-leverthe counter weighed lever 51, of the carriage block 50, is elevated tobring the threaded face of the depending portion 50a, out of engagementwith the threaded timer shaft 46, so that the carriage block may beshifted or returned to its initial position on the carrier shaft 45, asindicated in the drawings.` An adjustable stop block GS, on the carriershaft 45,

adapted to be adjusted for limiting the movement of the carriage blockon the carrler shatt 45.
